Rota: This third dose may be needed, depending on the brand of vaccine used in previous rota immunizations.

6 months and annually

Influenza: The vaccine is recommended every year for children 6 months and older. Kids under 9 who get a flu vaccine for the first time will receive it in two separate doses at least a month apart. Those younger than 9 who have been vaccinated in the past might still need two doses if they have not received at least two flu vaccinations since July 2010.

The vaccine can be given by injection with a needle (the flu shot) or sprayed into the nostrils (nasal spray or nasal mist). The spray is preferred for healthy children 2 to 8 years old if it's available. If it's not available, kids should get the flu shot.

College entrants

Meningococcal vaccine: Recommended for previously unvaccinated college students who will live in dorms. One dose is enough for healthy college students whose only risk factor is dorm living.

Special circumstances

HAV is also recommended for kids 2 years and older and adults who are at high risk for the disease. This includes people who live in, travel to, or adopt children from locations with high rates of HAV; people with clotting disorders; and people with chronic liver disease. The vaccine also can be given to anyone who desires immunity to the disease, and is useful for staff at childcare facilities or schools where they may be at risk of exposure.

Influenza vaccine It's especially important for kids at risk of developing health problems from the flu to be vaccinated. High-risk groups include, but aren't limited to, kids younger than 5 years old, and those with chronic medical conditions, such as asthma, heart problems, sickle cell disease, diabetes, or human immunodeficiency virus (HIV). The nasal spray isn't recommended for kids with certain medical conditions or pregnant women.

Meningococcal vaccine can be given to kids as young as 2 months old who are at risk of contracting meningococcal disease, such as meningitis. This includes children with certain immune disorders as well as those who live in (or will be traveling to) countries where meningitis is common. This vaccine also should be given to teens 13 and older who did not receive it in childhood.

Pneumococcal vaccines also can be given to older kids (age 2 and up) who have immunocompromising conditions, such as asplenia or HIV infection, or other conditions, like a cochlear implant.
